f n) all whom it may concern:

Be it known that I, HOWARD H. DUDLEY, a citizen of the United States, residing at Kansas City, in the county of Jackson and 'State of Missouri, have invented certain new and useful Improvements in Supports for "fthe OrossingRails of Railroads, of which the following is a specification.

My invention relates to an improved sup- }10 ort for the crossing rails of railroads and tlfe method of constructing the same.

.The object of a crossing support which will firmly support the rails and will not readily permit the i entrance of water into the ground ther object of my invention is to pro- 6 ,r method for constructing a crossing .ort which can be quickly and economicpcarriec'l into efiect, and which will prof ie a support practically impervious to the ntrance thereunder of moisture. Other novel features of my invention are hereinafter fully described and claimed.

1 In the accompanying drawings illustrating my invention, Figure 1 is a perspective view of my improved crossing support, portions of the ties and ballast being broken so away. Fig. 2 is a vertical sectional view on I. the dotted line a-b of Fig. 1. Fig. 3 is a top view of the concrete base, a portion of which is broken away to disclose the chan nels for the webs.

Similar characters of reference denote similar parts.

1 denotes the crossing rails mounted upon horizontal cross ties 2 which in turn are supported upon ballast 3 of broken rock or similar material.

The ballast 3 is mounted on a horizontal i base 4: of cementitious material, such as concrete. The base t is provided with vertical webs 5 which extend downwardly into chanis nels 6 out into the ground. to receive them. i The webs 5 are preferably at the edges of the base l and serve to keep mo1sture from passing under the base at its edges.

also serve to prevent lateral movement of the base upon the ground. I

In constructing the crossing a ti are first dug in the grou t. I. meal W1 the ground the channels after which i in a flatl Specification of Letters Patent.

my invention is to provide I under the l supp rt, which will firmly retain its position, l which can be economically constructed. 1

sheet between and extending into and filling the channels. Upon the base so formed is placed ballast of broken rock or similar material, and upon the ballast are placed horizontally the ties 2 which support the crossing rails 1.

By the insertion between the ties and the concrete base of the ballast danger of breaking of the base by train pressure on the rails is eliminated and a more flexible support for the rails is provided.

My invention may be modified, within the scope of the appended claims, without departing from its spirit.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. A crossing support comprising ties which support crossing rails, a horizontal cementitious base, and ballast supported on said base and supporting said ties.

2. A crossing support for rails compris ing a base of oementitious material having a horizontal body provided with one or more vertical webs, ballast mounted on said base, and horizontal ties supported on said ballast and supporting the crossing rails.

3. A support for crossing rails comprising a base of cementitious material having a horizontal body and a plurality of downwardly extending webs some of which are disposed at angles to others, ballast supported upon said base, and horizontal ties supported on the ballast and supporting the crossing rails.

4. A support for crossing rails comprising a base of concrete, ballast mounted on said base, and horizontal ties supported on said ballast and supporting the crossing rails.

A support for crossing rails comprising a horizontal concrete base having one or more vertical webs extending downwardly,

t ballast mounted on said base, and horizontal. ties supported on. said ballast and supporting the crossing rails.
